COVER FOR TANKS.

l v v 7 Application filed January This invoi1tionrelatcs to a cover adapted to be placed on a tank oi receptacle from which oils or liquids, preferably of a vol-a tile nature, are to be rcn'io'ved. v Certain tanks in which gasoline and other volatile liquids are transported have a top or top portion comprising a circular flange or rim and also have an aperture through said top, in which a pipe s dlsposedfor removing the gaso- 11116. When the gasoline or other volatile liquid is so removed there usually quite a space around the tank and considerable leakage and evaporation of the volatile liquid occurs. V

It is an object of this invention, therefore, to provide a device adapted to be used in connection with such a tank which will fit closely thereover and around the removing pipe so that leakage and evaporation ofthe liquid in any appreciable amounts will be prevented. j Y

It is a further object of the invention to provide such' a device comprising a coverhaving a flange projecting downwardly therefrom adjacent its edge with means below the flange to closely engage the top of the tank, said cover also having an aperture therethrough, and means carried adjacent the aperture to, closely engage the pipe e1;-

tending into the tank.

It is also an object of the invention to provide such a cover, as set forthinthe preceding paragraph, having a portion adjacent one edge pivoted for outward swinging movement, said cover having a lateral opening extending to said aperture which is exposed when said swinging portion swung outwardly whereby the covercan be. placed on the tank with thepipe in position and the pipe can be closely engaged when the swinging portion is again swung inwardly.

These and other objects and advantages of the invention "will be fully set forth n theiiollowing description made in connection with the accompanying drawings in which like reference characters refer to the sai'ne parts tl -ongimutche different views; and in which, V

Fig. 1 is a plan view of the device showin the removable pipe in cross section and showing the swinging portion ofthe cover in a different position in dotted lines;

Fig. 2 is a view partly in side elevation and partly in vertical section; and.

Fig. 3 is a vertical section taken on the line 3-3 otFlg. 1.

Referring to the drawings, the top of the tank or receptacle in which liquid is to be transported isshown as 4, said tank having top portion 5 upturnedat its edges and forming with the side of the tank a circuii'iferential upstanding flange port-ion if;

Said top 5 also has an aperture'5' therethrough surrounded by an upstanding flange 5 which may be closed by any's'uit'able block or cover and which, in the embodiment of the, inventionillustrated, is shown as being interiorly threaded to receive a closurememher. When the liquid is to be removed from 'the tank a pipe 7 maybe placed down into the tank through the opening 5, the liquid ping pumped through the" pipe '7 and directed to the desired place; j

, In accordance with the present invention, a cover member S is provided made of sheet material, preferably metal, and which will be made ofthesame shape as "the tank 4%, which, in theembodiment of the'invention, is shown as circular. flange 9 projecting downwardly therefrom, adjacent its edge, which flange is angular in cr'osssectio'n and riveted or otherwise suitably [secured to the cover 8." Outside of th'eflangeQ, a gasket'ringlO'is disposed, 'vhich'fWh'en the cover is in position onthe tank, is adapted to closely engagethe flange l The fl'at toplofjcover8 has an aperture 8 formed therein ofsemi circular shape at its inner portion havingstraight sides tan gent to said semi-circular portion and sub stantially parallel "to aadius passing through the center-of said semi-circular portion. The o ening 18 extends to the edge of the cover '8; At theinner side ofthe 'opening 8 an angular flange 11 of semicircular shapes securedhaving inturned spaced pointed portions 11*, said points overhanging the portion between the vert1- cal wall of the flange 11 and ft-h'e edge of'the opening 8. A semi-circular gasket member The cover 8 has aill) loo

j acent the opening 8. The member 13 also has a semi-circular opening 13 at its inner side which is surrounded a short distance from its edge by the upstanding semi-circular flange 17 which has inwardly directed points 17 the flange 17 being substantially concentric with the flange 11, the'semi-circular portion of aperture 8-also being concentric with the opening 13. A gasket member 18 of semi-circular form is clamped between the points 17 and the top of member 13. The cover 8 has a handle 19 disposed at its center by which the same can be manipulated.

In operation, after the pipe 7 has been disposed in the tank for the removal of the liquid the cover 8 is placed in position. This can be done by swinging outwardly the section 13, as shown in dotted lines in Fig. 1, and moving the cover into place laterally,

' the pipe 7 passing through the opening 8 The gaskets 10 and 16 will then be pressed down on the top of flange e and the member 13 will then be swung to closed position with the latch 15 engaged with pin 14. \Vhen this is done the gaskets 12 and 18 will closely engage the pipe 7. A tight closure is thus provided for the tank 4: and in the opening 5 therethrough and no substan tial portion of the liquid can' leak or evaporate.

From the above description it is seen that applicant has provided a very simple and efficient device for preventing leakage and evaporation from liquid stored and transported in tanks. The device is simple and easily constructed and can be produced at low cost. By the use of the same a great saving in oil and other liquid is accomplished. The device has been amply demonstrated in actual practice and found to be very successful and eflicient.

It will, of course, be understood that Various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of applicants invention, which, generally stated, consists in the novel parts and com bination of parts disclosed and defined in the appended claims.

What is claimed is:

1. In a container having an aperture therein through which a pipe is adapted to extend, an angular semi-circular flange secured to the container adjacent an edge of said aperture, a semi-circular closure plate pivoted to said container adjacent another edge of said aperture, an angular semi-circular flange mounted on said closure plate and a split ring of packing material secured to each of said flanges, said split rings of packing material being adapted to co-operate to clamp about a pipe extending through said aperture and form a fluid tight joint between the container and the pipe when said closure plate is swung toward the flange secured to said container, said flanges having a plurality of inwardly extending pointed portions at their upper inner edges securing said split rings of packing material to said flanges.

2. In a container having an opening therein at the joint between one side and one end thereof, a flange fixed to the end of the container adjacent the inner edge of the open portion at the end of the container, a closure member pivoted to the container and adapted to close the open portion at the side of the container and the outer part of the open portion at the end of the container, a split ring of packing material carried by said flange, a split ring of packing material carried by said closure member, and means for holding said closure member in closed position, said split rings of packing material being adapted to encompass a pipe inserted within said aperture to provide a fluid tight joint between the container and the pipe.

3. In a container having an aperture through one end adjacent one side thereof, said container being capable of receiving a pipe through said aperture, said side being cut out adjacent said aperture to form a side opening in said container communicating with said aperture, a flange fixedly secured to said top adjacent the inner side of said aperture, a swinging plate pivoted to said top, a pad of packing material secured to the lower side of said plate and adapted to close the side opening in said container as said plate is swung inwardly, a flange carried by said plate, and pads of resilient ma terial carried by each of said flanges, said last mentioned pads being adapted to cooperate to tightly embrace a pipe inserted through said aperture as said plate is swung inwardly. i

In testimony whereof I aflix my signature.
